Specification of Letters Patent.

Patented June 28, 1921.

Application filed August 26, 1919. Serial No. 319,923.

where great flexibility is required. These ropes have usually been formed by laying a plurality of wires or strands about a central strand of manila or like fiber.

The especial object of the present invention is the provision of a cheap, strong and easily manufactured core construction adapted to take the place of the more expensive manila cores.

In the accompanying drawings forming part of the specification there is shown for the purpose of illustration a core of the preferred form embodying all the features of the invention, and this construction will now be described in detail and the features forming the invention then specifically pointed out inthe claims.

In the drawings,-

Figure 1 is a plan view of a rope having one layer of strands with one end of the rope strands broken away and some of the disks separated to show the core construction; and

Fig. 2 is a cross section of the rope.

Referring to the drawings, A is a suitable central wire or support on which a plurality of comparatively thin disks B, formed of fiber, leather or other cheap material of such strength as to support the pressure of the wires and of suflicient diameter to equal that desired for the core, are loosely assembled by being strung side by side. These disks form the rope core, and the rope rope, and the central passage thus formed provides convenient means forthe passage of lubricant to the spaces between the disks. While the invention is shown and described in connection with a rope formed of strands consisting of a plurality of small wires, as usual in wire rope constructions, it will be understood that the invention is not so limited as the same is adapted for uses in which the strands are of single wires. It will be understood, also, that the invention is not limited to constructions in which the rope strands are laid directly on the disk core, but that the rope may be built up on the core in any usual or suitable manner.

What I claim is:

1. A wire rope having a core comprising a plurality of disks, substantially as described.

i 2. A wire rope having a core formed by a "small central support and a plurality of m' hand.
